This interaction leads to the conformational change of antithrombin, increasing the time of its anticoagulation activity several-fold.

Factor Xa dimerization competes with prothrombinase
Mouse Factor Xa - Innovative Research - innov-research.comTherefore, the excess amount of factor Xa remaining in the sample is inversely proportional to the original amount of LMWH or UH.It may be ordered periodically to monitor UFH therapy, especially when a person is not responding as expected to UFH or when the PTT is not useful.
Factor ixa - definition of Factor ixa by The Free Dictionary
Factor Va competes factor Xa off of inactive factor Xa dimers to amplify thrombin production, both because it releases dimer inhibition and because of its cofactor.
Anti Factor Xa |authorSTREAMIt is typically collected about 4 hours and 3 hours after a LMWH and fondaparinux dose is given, respectively, when the level in the blood is expected to be at its highest level.The anti-Xa assay is suitable to monitor fondaparinux and danaparoid if the appropriate standard curve is used.This methodology incorporates the addition of known amounts of factor Xa and antithrombin to the sample.

Measuring Anti–Factor Xa Activity to Monitor Low-MolecularLMWH is prepared from UH via filtration and enzymatic or chemical depolymerization.The most commonly used methodology is the chromogenic assay, which uses a chromophore-linked substrate of factor Xa.
